Water pollution is a big issue, and so far there isn’t one single system capable of reliably filtering toxic heavy metals. These are either too small, or selectively filter certain metals when polluted water often contains a mix. Researchers at ETH Zurich claim they’ve hit a breakthrough. Using cheap, readily available materials they designed a filter that can retain over 99% concentration of mercury, gold cyanide or toxic potassium, to name a few. It can also absorb radioactive waste and help recycle gold.

The Earth contains a lot of iron, but it is not alone in the solar system in that aspect. Venus, Mars, the Moon and asteroids such as Vesta all have iron in their structure, but Mercury is the champion in that aspect: about 70 percent of its mass is iron! Now, researchers believe they have found why Mercury is so

Researchers have developed a three dimensional atlas which shows the concentrations of iron dissolved in the world’s oceans. This monumental achievement can be very valuable for scientists, but also for policy-makers. Why is mapping iron in the oceans such a big deal ? Well for starters, iron plays a crucial role in the oceanic carbon cycle, as it is a

When Swedish researchers published this theory of theirs, nobody took it seriously. Without paying much attention to the scientific community, they pursued and tried to prove what they were claiming. It seems now they have managed to present evidence which supports their way of viewing Earth’s internal core. The findings may be of significance for our understanding of the cooling
